The Current in the world have the same problem. That is the greenhouse effect. This is the big problem for every people. This is not only endanger for human, but also endanger for the animal.
For example, the polar bear. The polar bear is live in the Arctic. Arctic is a ice world. And greenhouse effect can let the ice to melt. Than the ice can be fewer and fewer.
